1. Area of triangle
1/2(10)(12)=60
There are two triangles, so multiply by 2
=120

2. Find area of the rectangles
This is an isosceles triangle, so the two rectangles are congruent
(2)(13)(3)=78

3. Find area of bottom rectangle
10(3)= 30

4. Add everything up
120+ 78 + 30= 228

Therefore the surface area of this prism is 228

I hope i helped :)

Assume that random guesses are made for ninenine multiple choice questions on an SAT test, so that there are nequals=99 trials

ValentinkaMS [17]

Answer:

The probability that the number of correct answers is 4 is 0.2461.

Step-by-step explanation:

Let <em>X</em> = number of correct answers.

The probability that an answer is correct is,P (X) = <em>p</em> = 0.50.

The total number of questions is, <em>n</em> = 9.

The event of an answer being correct is independent of the other answers.

The success of each trial is defined as a correct answer with equal probability of success for each trial, i.e. 0.50.

The random variable <em>X</em> follows a Binomial distribution with parameter <em>n</em> = 9 and <em>p </em>= 0.50.

The probability mass function of <em>X</em> is:

$P(X=x)={9\choose x}\times0.50^{x}\times (1-0.50)^{9-x};\ x=0,1,2,3...$

Compute the value of P (X = 4) as follows:

$P(X=4)={9\choose 4}\times(0.50)^{4}\times (1-0.50)^{9-4}$

$=126\times 0.0625\times 0.03125\\=0.24609375\\\approx 0.2461$

Thus, the probability that the number of correct answers is 4 is 0.2461.

Evaluate the expression for the given value of the variable. | − 4 b − 8 | + ∣ ∣ − 1 − b 2 ∣ ∣ + 2 b 3 ; b = − 2

Nastasia [14]

Answer:

-11

Step-by-step explanation:

The given expression is:

$|-4b-8|+|-1-b^2|+2b^3$

= $|-(4b+8)|+|-(1+b^2)|+2b^3$

= $4b+8+1+b^2+2b^3$

= $4b+9+b^2+2b^3$

Substituting the value of b=-2 in above expression, we get

= $4(-2)+9+(-2)^2+2(-2)^3$

= $-8+9+4-16$

= $-11$

Thus, the value of the given expression is -11.
